Horizontal Agitator

Hydromixer

The Series Champion.

Long-proven and developed for demanding substrates with high dry matter contents.
Hydromixer
A – AMixing element view
Established for Years
Over 1,000 units in use worldwide
High Dry Matter Contents
Powerful mixing even with challenging substrates
Robust Design
Powerful drive for large-volume tanks
Functional principle

Full Performance for decades.

The Hydromixer is our proven classic and has been successfully used in numerous biogas plants for many years. Thanks to its generously sized paddle blades, it is ideally suited for breaking up floating layers. At the same time, it ensures effective mixing of substrates with low and high dry matter contents, thus contributing to stable process conditions in the digester.
